Why does the transit method present a geometric requirement that biases detection towards planets in small, tight orbits?

Answer

Small, tight orbits are the configurations most likely to align edge-on with Earth.

The geometric requirement for alignment means the transit method is inherently biased towards finding planets in small, tight orbits around their stars, as these configurations have the highest probability of aligning perfectly with our line of sight from Earth.
